Step-by-step explanation:
Marked price (MP) = x
Selling Price after discount (SP after discount)
= Rs. 1350
Discount rate = 25%
Now
SP after discount = MP - discount % of MP
1350 = x - 25 % of x
1350 = x - x / 4
1350 = 3x / 4
1350 * 4 =3x
5400 / 3 = x
Therefore x = Rs. 1800
The marked price is Rs. 1800
Given, Earth's diameter is approximately 12,760,000 meters.
This number in scientific notation will be 1.276 × 10⁷
Answer:
4a2 + 4a + 1 = (2a +1)^2 = (2a + 1)(2a + 1)
4 − 4a + a2 = (2 - a)^2 = (2 − a)(2 − a)
4a2 − 4a + 1 = (2a -1)^2 = (2a − 1)(2a − 1)
4 + 4a + a2 = (2 + a)^2 = (2 + a)(2 + a)
Step-by-step explanation:
Answer:
a. 4/13, b. 1/2, c. 3/52, d. 8/13
Step-by-step explanation:
a.
aces in a deck: 4
face cards in a deck: 12
(4+12)/52 = 16/52 = 4/13
b.
even numbers in a deck: 26
26/52 = 1/2
c.
only 3 face cards that are diamonds
3/52
d.
reds in a deck: 26
face cards in a deck: 12
face cards that are red: 6
(26+12-6)/52 = 32/52 = 8/13
